The Entry Hole Dialog Box
The Setup Entry Hole section of the Entry Hole dialog box contains the following options.
Hole Diameter—The expected size of the drill to use for drilling the Entry Hole. Type the diameter value in the text box.
Hole Location
• Place—Define the Entry Hole placement either automatically, or using the X and Y coordinates of the Program Zero coordinate system.
• Corner—Define the Entry Hole placement with respect to a corner of the parent feature.
Place Entry Hole
These options appear when the Place option is selected for Hole Location:
• Automatic—When this checkbox is selected, the hole is placed in the approximate center of the parent feature. To specify a different placement, clear this checkbox and type the desired values in the X Direction and Y Direction text boxes below.
• X Direction—Type the X coordinate of the Entry Hole axis with respect to the Program Zero coordinate system.
• Y Direction—Type the Y coordinate of the Entry Hole axis with respect to the Program Zero coordinate system.
Corner Entry Hole
These options appear when the Corner option is selected for Hole Location:
• Corner—Click
and select a corner of the parent feature (either an edge or a rounded surface). In a rounded corner, if the radius of the hole is less than the corner radius, the system places the Entry Hole coaxial with the corner round. Otherwise (for example, in a sharp corner), the system places the Entry Hole based on its diameter, tangent to the adjacent walls. To modify this placement, use the
Wall Offset option below.
• Wall Offset—Type the minimum offset of the Entry Hole from the walls adjacent to the selected corner.
Entry Hole Depth
Define the Entry Hole depth using one of the two options:
• Floor Offset—Specify how far above the floor of the parent feature the Entry Hole ends. By default, this offset is 0, and the Entry Hole depth equals the depth of the parent feature.
• Enter Depth—Type the Entry Hole depth. By default, it is the depth of the parent feature.
